Portable Barrier Device

ABSTRACT

A portable barrier device and method of use are disclosed. The device may include a primary body unit, which may include one or more light sources, reflectors, and signs, any of which may be permanently or removably attached, such as by the use of magnets or slots. The device may include a power source, such as a battery, or it may be externally powered. The device may be used to power the light sources or to power or charge peripheral devices. The device may include one or more legs which may be removably attached or may rotate, slide, or otherwise fold out or extend to support the device and create a portable barrier. The device may also include one or more handles to aid in transport of the device. The legs may be manually deployed or using single-handed operation.

This application claims the priority of U.S. Provisional Patent Application No. 62/651,065 filed on Mar. 30, 2018, the disclosure of which is incorporated herein in its entirety.

BACKGROUND

The present disclosure relates generally to a portable barrier device. More particularly, the present disclosure relates to a device, and associated method of use, which can be stored and transported in a reduced overall volume, then deployed at a location where a barrier or other notification is desired. The device can also include lights, a power source, and additional components and methods of notification.

When police need to set up mobile checkpoint, such as for sobriety checks or due to accidents, it can be desirable to have a barrier to aid in direction of traffic. Lighting may also be desirable, such as at night or when notification of ongoing traffic is desirable. Such portable barriers may also be beneficial to other forms of traffic control, such as due to events with large numbers of people present and road work. Current methods and devices either do not provide adequate barriers and notification or are large and cumbersome to transport, often requiring set-up times which may not always be available to the user. Current devices which may fold or disassemble into smaller components are cumbersome and time-consuming to assemble and provide inadequate support and notification options. Separate light sources or other components or accessories which may require a primary or supplemental power supply additionally require separate power supplies and create an even more time-consuming assembly process.

Current methods of transporting, storing, and assembling barrier devices require time to assemble which may not be available to those needing to use them, and still remain inadequate for directing traffic and providing notification to ongoing traffic or passersby.

SUMMARY

The present disclosure relates generally to a portable barrier device. More particularly, the present disclosure relates to a device, and method of use, which can be easily stored and transported in a reduced overall volume and can be deployed quickly and easily at a location where a barrier or other notification is desired. The device can also optionally include lights, a power source, and other components for and methods of notification which can further aid in directing traffic, stopping traffic, or notifying traffic of important information, such as upcoming hazards or alterations to established traffic routes.

Police often have a need for setting up quick or impromptu sobriety checkpoints, traffic stops, or traffic redirection due to accidents. Similarly, repair truck drives or tow truck drivers often need to quickly set up a barrier with a light source to alert oncoming traffic of an accident, a disabled vehicle, or other road hazard. A driver whose car has broken down may also need to quickly set up a warning for oncoming traffic. Road works crews also often need to quickly set up barriers or notification means, which may also need to be moved regularly and at varying intervals as work progresses. In such scenarios, a portable barrier that can be set up quickly and easily, is stable enough or can be stabilized or levelled so as to resist winds or varying uneven terrain, and may have including lighting and power for powering or charging devices, may be the difference between successfully warned traffic and potential loss of life.

In one embodiment, the portable barrier device includes a primary body unit. It may include and at least one leg, which may be attached to the primary body unit in such a way as to be extendable from the primary body unit. The one or more legs can rotate away from the primary body unit in order to extend, may rotate out from at least partially within the primary body unit, or may slide out or otherwise slide to extend away from the primary body unit. The one or more legs may also extend from the primary body unit using a combination of the above means.

In one embodiment, the portable barrier device may include only a single leg, which has a foot in contact with the ground which provides a sufficient footprint, either directly or through additional attached components, to support the portable barrier device while also extended sufficiently beyond the center of gravity of the portable barrier device where the portable barrier device has sufficient stability to stand alone without additional support. In other embodiments, the portable barrier device may include two legs, three legs, or any other number of legs that may be desirable to a user or manufacturer. In a preferred embodiment, the portable barrier device includes four legs, which may extend directly down from the primary body unit and be substantially perpendicular to the ground, or may extend so as to create an acute angle with the ground, thus increasing the footprint of the portable barrier device relative to the primary body unit and improving stability.

The portable barrier device may include at least one locking feature which is configured to lock one or more legs in a deployed or extended configuration, or to at least resist motion of one or more legs back to an undeployed configuration. The portable barrier device may also include a locking feature which is configured to resist unintended deployment of one or more legs from an undeployed configuration, such as a locking brace, a clip, a pin, a ball plunger, or other means known in the art. The portable barrier device may also include a feature which only slightly resists unintended deployment of one or more legs, such as a high friction surface which contacts at least one leg when in an undeployed configuration, or a light press fit or light snap fit. In another embodiment, one or more legs may resist unintended rotation or sliding by means of tight tolerancing of interfacing components, such as a tight rotational fit or tight slip fit. In another embodiment, one or more legs may be prevented from deploying by means of gravity. One method using such an embodiment is where the portable barrier device is stored in an upside-down orientation, with the top surface on the bottom of the storage location. One or more legs may stay in an undeployed configuration until the portable barrier device is rolled or otherwise rotated into a rightside-up orientation, at which time the one or more legs may deploy based on their own weight. In another embodiment, the portable barrier device may include one or more movable components, such as a pawl or other at least partially flexible, rotatable, slidable, or otherwise movable locking features. A button, slider, lever, or trigger may be used to force the component to release one or more legs, such as against tension or force from a press fit or spring.

The portable barrier device may include at least one cross-connector which may aid in supporting at least one leg in a deployed configuration. It may also include at least one cross-connector which may connector multiple legs, supporting each in a deployed configuration. The cross-connector may also include a locking feature to aid in maintaining a deployed configuration of one or more legs and may comprise multiple components.

In one embodiment, the primary body unit comprises an internal unit and an external unit. The internal unit may seat at least partially within an at least partially open volume within the external unit. The external unit may surround the internal unit to a substantial degree, or it may only cover some portions of the internal unit, such as where additional support is desirable, or where additional structures may be beneficial for attachment of additional components. Either the internal unit or the external unit, or both, may comprise multiple component units which may be connected directly or by means of the other respective unit, or may be a single piece. The primary body unit may also consist of a single unit without a separate internal unit and external unit.

The primary body unit may have a substantially trapezoidal cross-sectional profile, and it may also define a substantially trapezoidally-shaped open volume. The primary body unit may also have a substantially trapezoidal front profile or side profile. The primary body unit may also be substantially rectangular, either from a front perspective, a side perspective, or both. Other shapes for either profile may also be used, such as triangles, hexagons, octagons, ellipses, compound shapes, and other shapes that may be desirable.

When in an undeployed configuration, one or more legs may seat substantially or at least partially within an at least partially open volume within the primary body unit.

The portable barrier device may include one or more handles which can be located on any surface or feature of the portable barrier device, including on a top surface, one or more side surfaces, on a bottom surface, or connected within the internal volume of the primary body.

The portable barrier device may include one or more light sources, which may be configured in various shapes or sizes, and may be permanently affixed to the portable barrier device or may be removably attached. The portable barrier device may also include a battery to power the light source or other electronic devices, or the battery may be removably attached or otherwise connected. The portable barrier device may also include a power connector, which may be used to power peripheral devices, such as cellular phones or speakers. The peripheral devices may be powered by the battery that powers the light source, or by a different battery or other power unit or power source.

The portable barrier device may be configured to support at least one sign. The portable barrier device may include a clip or other feature configured to support a complementary feature on a sign. The portable barrier device may also be configured to retain a sign through a magnetic feature, such as by a magnet-backed sign which is attracted to the metal of at least a portion of the portable barrier device, or may include a magnet to support signs which include metal. The portable barrier device may also include at least one slot configured to receive a sign. The portable barrier device may also include retention features configured to retain other components, such as connectors configured to receive flags, posts, supplemental lighting, or solar collection cells.

The portable barrier device may be deployed by removing the device from storage, such as from a trunk or storage compartment, placing it at or near where the user wishes the device to be deployed, extending or rotating out at least one leg into a deployed configuration, and resting the device where it is desired. One or more legs may be locked in a deployed configuration. Optional leg extensions or feet, such as rotatable platforms, may also be included and deployed or otherwise adjusted to improve stability of the portable barrier device or to aid in levelling of the device. A light source may be activated to warn oncoming traffic, to direct oncoming traffic, or to make the barrier more noticeable. Signs, flags, or other notification components or methods may also be attached or used.

The method may include the use of a device which may include one or more of the features, steps, or components described herein. Any number of steps or elements may be used in conjunction with the method described, and various means for connections, gripping, storage, and protection may be incorporated.

It is to be understood that the above-mentioned steps and features and the steps and features yet to be explained hereinafter can be used not only in the respectively mentioned combinations but also in other combinations or alone without departing from the context of the present invention.

However, it will be apparent to one skilled in the art that the present invention may be practiced without the specific details. In other instances, well-known features or those previously described are omitted or simplified in order not to obscure the illustrative embodiments.

Various operations may be described as multiple discrete operations, in turn, in a manner that is most helpful in understanding the present invention, however the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation. In some instances, structures and devices may be shown in block diagram or flow chart form or described without complicating figures in order to facilitate describing the disclosed subject matter.

FIG. 1 shows an isometric view of an embodiment of the portable barrier device 100 of the present disclosure. The device 100 may be used where it may be desirable to set up a barrier, including where a barrier may be beneficial on a temporary basis or for a specified situation. The barrier device 100 may include a primary body unit 110. The primary body unit 110 may extend along a length which is desirable to be sectioned off by the barrier device, or it may extend along a shorter length where such a length may be sufficient to draw the notice of others to the barrier device's 100 presence. The barrier device 100 may also be used in conjunction with other items or devices, such as additional barrier devices 100, cones, flags, or more permanently located structures. In one embodiment, the primary body unit 110 may be 34″ long, 8″ wide at either the top or bottom, and 9″ tall, and the deployed portable barrier device 100 may be 34″ tall when in a deployed configuration, though the primary body unit 110 and the portable barrier device 100 may be longer or shorter, wider or less wide, and taller or shorter when deployed or opened, depending on the materials being used, desired application of the portable barrier unit 100, desired strength or stability, or user or manufacturer preference. In another embodiment, the primary body unit 110 may be substantially rectangular in cross-section, where the width is less than the height and the width at the top and bottom are identical or similar. Any commercially reasonable height, length, and width may be used, including significant variations from the listed embodiments. The primary body unit 110 may be substantially rectangular when viewed from the front, as shown in FIG. 2, or may be other shapes, including, but not limited to, trapezoidal or triangular. The primary body unit 110 is shown as having a substantially trapezoidal cross-section when viewed from the side, as seen in FIG. 03, though it should be understood that other cross-sectional shapes may also be used, such as rectangular, octagonal, hexagonal, triangular, elliptical, compound shapes, or other shapes.

The portable barrier device 100 may include one or more legs 120. The legs 120 may extend away from the primary body unit 110 at an angle so as to be perpendicular to the ground when in an open or deployed configuration or may extend at an angle from the body unit which is not perpendicular to the ground, such as 60°. In the embodiment shown, each leg 120 extends at an angle so as to create a larger base footprint at the point of contact with the ground than that of the primary body unit 110, extending beyond the center of gravity of the portable barrier device 100 relative to the ground and improving the stability of the portable barrier device 100. It should be understood that other orientations of one or more legs 120 may also be used, including configurations where one or more legs 120 extend beyond the footprint of the primary body unit 110, improving stability of the portable barrier device 100, while one or more legs 120 extend perpendicular to the ground, or even at an angle extending within the footprint of the primary body unit 110, allowing the deployed portable barrier device 100 to fit within smaller spaces when deployed, or allowing a person to be in closer proximity to the portable barrier device 100, or allowing the portable barrier device 100 to maintain improved stability over uneven or angled surfaces. In some embodiments, the angle of one or more legs 120 relative to the ground may be variable or adjustable.

The legs 120 in the embodiment of FIGS. 01-03 are shown with a substantially rectangular cross-section, though it should be understood that other shapes may also be used, including circular or cylindrical forms, trapezoidal cross-sections, or others. One or more legs 120 may also have a compound or hybrid shape, such as including recesses, slots, or keying features to allow for improved sliding of extending components or to improve the rigidity of the leg 120. The legs 120 are also shown with a substantially hollow area, such as that created by forming the legs 120 from bent sheet metal or extruded metal stock. It should be understood that the legs 120 may also be substantially solid, or may have other shapes and volume specifications, such as those conducive to molding or manufacturing by means of extrusion. The legs 120 may also feature additional support plates or foot plates 1330, as well as connectors if smaller sections are to be combined in creating a complete leg 120. These components may be attached by means of welding, riveting, screws, bolts, adhesives, slip fits, press fits, or other means known in the art.

The portable barrier unit 100 may include one or more cross-connectors 125, which may be used to strengthen or support the legs 120 when in an open configuration or to aid in maintaining the open configuration. The cross-connectors 125 may themselves be formed of multiple components, such as a large cross-beam 126 and a small cross-beam 127. The small cross-beam 127 and large cross-beam 126 may be rotatably or slidably connected to each other and may be rotatably or slidably connected to one or more legs 120, enabling maintaining at least one point of connection to at least one leg 120 when one or more legs 120 are in a folded configuration. The portable barrier device 100 may include one or more locking features which may either lock the large cross-beam 126 and small cross-beam 127 in position relative to each other when the legs 120 are in a deployed configuration, lock the cross-connectors 125 in position relative to at least one leg 120 when the legs 120 are in a deployed configuration, or both. One or more of a range of locking features known in the art may optionally be used, such as spring plungers, ball plungers, friction fits, cams, pins, levers, and more.

Though the cross-connectors 125 are shown connecting a front leg 120 to a rear leg 120, in alignment with anticipated forces which may potentially be applied to the portable barrier device 100, it should be understood that cross-connectors 125 may also be used in other configurations, in other locations, or connecting one or more legs 120 to other components. Cross-connectors 125 may also be used to connect one front leg 120 to another front leg 120, one rear leg 120 to another rear leg 120, or connecting at least one leg 120 to the primary body unit, providing support and strength in whatever directions and orientations may be desirable or beneficial. Additional cross-connectors 125 may also be used to connect cross-connectors 125 to each other, such as between a cross-connector 125 on one side to that on another side, or to connect a cross-connector 125 to the primary body unit 110. One or more cross-connectors 125 may also be removably attached, such as when the portable barrier unit 100 is being unfolded and deployed or closed or stored.

Though the legs 120 are shown as being rotatably connected to the primary body unit 110, the legs 120 may alternatively be connected and extendable in a slidable fashion. The legs 120 may slide to extend from the primary body unit 110, may include extension features which allow the legs 120 to extend to greater length so as to allow a taller configuration of the portable barrier device 100 or to allow for different leg 120 lengths to accommodate uneven or angled surfaces, or may rotate out into an unfolded configuration and may then additionally extend to a longer length and a greater height of the portable barrier device 100.

As shown in the embodiment of FIG. 4, the primary body unit 110 may include one or more connection or rotation points 140, or the connection or rotation points 140 may be included in a secondary unit 112 within the primary body unit 110. FIG. 5 shows a bottom view of the secondary unit 112, including an at least partially open internal volume 150, while FIG. 6 shows a front cross-sectional view of the secondary unit 112. The secondary unit 112 may include one or more locking features 148 which may lock one or more legs 120 in a deployed or unfolded configuration. The locking features 148 may be post or pins which mate with complementary features in the legs 120, may be brackets, light-press-fit features, may be openings such as holes, detents, or slots, configured to receive mating pins, ball plungers, spring plungers, or other features of the legs 120, or may be other locking means known in the art.

The primary body unit 110 may include an exterior body unit 111, which may at least partially cover or encompass the secondary unit 112. As shown in FIG. 7, the exterior body unit 111 may be shaped substantially similarly to the secondary unit 112, though it should be understood that other shapes and forms may also be used, including shapes which only cover or contact parts of the secondary unit 112, such as where additional support, strength, or protection of the secondary unit 112 is desirable, or where the exterior body unit 111 provides connection points or surfaces for other items which may be included with or attached to the portable barrier device 110. FIG. 8 shows a bottom view of the exterior body unit 111, and FIG. 9 shows a front cross-sectional view of the exterior body unit 111. The exterior body unit 111 may be removably connected to the secondary unit 112 or one or more legs 120, or may be attached to the secondary unit 112 or one or more legs 120 by means of adhesives, welding, rivets, screws, bolts, snap fits, press fits, friction fits, or other means known in the art.

The portable barrier device 100 may be folded or collapsed into a folded configuration or may have components such as legs 120 or cross-connectors 125 removed. In such a configuration, the portable barrier unit 100 may be easier to transport or store, such as where the portable barrier unit 100 is stored in the trunk of an automobile, in the bed of a truck, behind a seat in an automobile or truck, or in a storage compartment. FIG. 10 shows an embodiment of the portable barrier unit 100 in a folded configuration. As shown in FIG. 11, the portable barrier unit 100 may be folded so that no features extend outside of the volume of the primary body unit 111. FIG. 12 shows a bottom view of the embodiment of FIG. 10, in a folded configuration. The legs 120 may be folded within an internal volume 150 of the primary body unit 110, and specifically within an internal volume 150 of the secondary unit 112. The cross-connectors 125 may rotatable fold to allow for the legs 120 that are connected by the cross-connectors 125 to be in closer proximity than when they are in an unfolded configuration, though it should be understood that the cross-connectors 125 may also slide or disconnect at one or more connection points 140. Though the cross-connectors 125 are shown folding in an asymmetrical orientation, it should be understood that they may also fold or rotate in a symmetrical orientation.

The portable barrier unit 200 may include one or more handles 260 or carrying features, as shown in FIGS. 13-14. The handles 260 may be flexible, and thus may be able to fold within the internal volume 150 of the primary body unit 210 when not in use, or may be substantially rigid and may slide or rotate within the internal volume 150 of the primary body unit 210. Though not shown, it should be understood that one or more handles 260 may be located on or adjacent to an exterior surface of the primary body unit 210 or legs 120, and may be slidablly, rotatably, removably, or permanently attached.

FIG. 15 shows an alternate embodiment of the portable barrier device 300 which includes light sources 370. Though two light sources 370 are depicted, it should be understood that only one light source 370 may be included, or any larger number of light sources 370 may also be included, or none at all, when desired. The light source 370 may be used to provide a constant light projection, a flashing or strobe light projection, or a consecutive patterned light projection, such as where there is simulated motion of the light pattern to direct traffic in a desired direction. The light source 370 may also be programmable, variable, and may also be removable if desired. The light source 370 may also be included in the exterior body unit 311, such as where different light patterns or effects may be desired for different situations and may be attached to the secondary body 311. The portable barrier unit 300 may include a power source, such as a battery, or may be attached to an external power source, such as by means of a power cord, to power the one or more light sources. Though a power source is not shown, different types of power sources known in the art may be used, such as batteries, fuel cells, and solar power panels. In a preferred embodiment, one or more batteries are located within the substantially open volume 150 of the portable barrier unit 300, though it should be understood that power sources may be located on the exterior of the portable barrier unit 300, on one or more legs 320, or elsewhere without deviating from the scope or intent of this disclosure.

The portable barrier unit 300 may also include one or more reflective surfaces 385 or attachable reflective components 385, such as shown on the legs 320 in the embodiments in FIGS. 15-16 and on the back of the primary body unit 310 in embodiment of FIG. 16.
